A blonde walked in to the department store, pointed and told a salesman, I want that TV.
"Nope, he said, "We don't sell to blondes."
She left, went back in with Red hair, Again, pointed and said, "I want that TV" "No, she was told , we do not sell to blondes"
A third time she entered, now dressed with a hat and a fake nose, "I want that TV". "No, we still do not sell to blondes."
Frustrated, she asked the salesman, "how can you tell I am a blonde?"
He said, "because, that is a microwave".
